Import Tips & Compliance
• ASTM D1045 test certificate mandatory showing acid number <0.1 mg KOH/g and color <50 Pt-Co
• Verify 2-ethylhexanol source purity; C8 alternatives disqualify from dioctyl orthophthalate specificity
• Density 0.983-0.986 g/cm³ at 20°C confirmation prevents density-based purity disputes

Dioctyl Phthalate (DOP)
Dioctyl phthalate (DOP), chemically bis(2-ethylhexyl) phthalate, is the most common dioctyl orthophthalate used as a plasticizer for PVC. It falls under HTS 2917.32.00.00 as it is a derivative of orthophthalic acid (1,2-benzenedicarboxylic acid) esterified with two octyl alcohol molecules. This aromatic polycarboxylic acid ester is supplied as a clear, oily liquid for industrial plasticizing applications.
Bis(2-Ethylhexyl) Phthalate (DEHP)
Bis(2-ethylhexyl) phthalate (DEHP), synonymous with DOP, is a branched-chain dioctyl orthophthalate plasticizer for flexible PVC products. Classified under HTS 2917.32.00.00 as the principal commercial form of dioctyl orthophthalates derived from phthalic anhydride and 2-ethylhexanol. Used extensively in wire insulation, flooring, and medical tubing.
Dioctyl Orthophthalate Stabilized Grade
Industrial-grade dioctyl orthophthalate with added epoxidized soybean oil stabilizer for enhanced PVC processing stability. Qualifies under HTS 2917.32.00.00 per Chapter 29 note (f) allowing stabilizers necessary for preservation/transport. The primary dioctyl orthophthalate structure determines classification.
High-Purity Dioctyl Phthalate 99.5%
Ultra-high purity dioctyl orthophthalate (99.5% min) for medical-grade PVC and sensitive electronics applications. Falls squarely under HTS 2917.32.00.00 as chemically defined dioctyl orthophthalate per Chapter 29 note (a). Supplied in nitrogen-purged drums to maintain specification.
